What nature is indicated by red colour in universal indicator?

Answer and explanation

Correct answer: Strongly acidic

Universal indicator changes colour according to the pH of a solution. Red occurs at the low-pH end of its colour range, showing a high concentration of hydrogen ions and therefore a strongly acidic nature. Hence option A is correct. Green is associated with near-neutral conditions, while blue or violet indicates basic conditions. The word salty describes taste or composition and is not a pH classification.
